i normally use middle-click to open in new tabs so i haven't tried this yet but have you checked this option in Tab Mix Plus?
Thanks for the help.
No, that setting didn't help — it's what I used to use to get what I like
So, I went to the dev build, and that page in TMP options is now quite different
After some fiddling around I now have middle-click/left-click working in reverse of the way that I prefer. After the first two or three thousand habitual mistakes I'll get the hang of it
@housetier: I toggled the setting you mentioned but that didn't seem to do anything. Restarted etc.
Toggled it back and now I have middle-click working. Beats me, but thanks.
Thanks again chaps!
